Currently, Proton Sheets documents cannot be saved into folders that are locally replicated via Proton Drive. This means any sheet created or edited in Proton Sheets remains cloud-only and is inaccessible from the local file system.

Being able to save a Proton Sheet directly into a synced folder — even as an auto-converted .xlsx — would greatly improve usability and make the ecosystem more practical for professional use.

Thank you for considering this.
